High-yield technical methods of long-branched apple sprouts in the third year

Abstract

The third-year high-yield technical method for long-branched apple sprouts on an arbor belongs to the technical field of fruit tree cultivation. The steps include: (1) building a garden; Start to smear when it starts to flow; smear on the buds that need to germinate; apply a small amount of medicine to each bud, and apply it evenly with light force; one bud at a time; continue to smear on the new branches formed after the buds germinate, and repeat; ( 3) Cultivate the trunk-shaped tree shape: when the seedling height is 100-120cm, find a bud in the axil of a large leaf near 90cm from the ground and 10-15cm below the growth point of the new shoot, and smear it on the bud. Apply buds every 1-2 leaves on the branches counterclockwise around the central axis until the seedlings reach a height of 180-200 cm; when each new shoot directly from the central axis grows to 30-40 cm, find side buds and back buds on it. Huazhibao; the new shoots directly meridian on the central axis are softened and angled in August-September; (4) Reasonable water and fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and specifically relates to a technical method for colonizing long-branched apple sprouts on an arbor anvil in one year, forming flowers in the same year, fruiting in the next year, and high yield in the third year. Background technique [0002] Apple is a worldwide fruit with strong ecological adaptability, high nutritional value, good storability and long supply cycle. Therefore, many countries list it as the main consumer fruit and strongly recommend it. Apples are produced in 84 countries on six continents in the world, with a total area of ​​5.5 million hectares 2 The total output is about 60 million tons, accounting for 11% and 12% of all fruits respectively. The common characteristics of the apple industry in advanced apple production countries are "Nine Bigs", "Ten Variations", "Six Highs" and "Three Natures", that is, large groups, large regional trials, large varieties, ...

AI Technical Summary

Problems solved by technology

[0016] Although the apple high-yield technologies reported in the above literatures have certain progress, generally speaking, there are still some defects: early fruiting is not outstanding, or large trees are needed for high grafting, or early high-yielding is not outstanding, or fruit trees are formed late , or more complicated, or need to cultivate large seedlings, the quality of short-branched varieties is not as good as long-branched (ordinary)

The cultivation mode reported in the literature is mainly shortened, that is, "single dwarf" or "double dwarf" cultivation, and there is no report of arborization cultivation of long-branched sprouts (semi-adult seedlings) in the third year after colonization.
